Ontario Child Support Calculator Shared Custody

This Ontario Child Support Calculator helps you estimate child support payments for shared custody arrangements. The calculator follows Ontario's child support guidelines, which are based on the income of both parents and the number of nights the child spends with each parent.

How to Calculate Ontario Child Support for Shared Custody

Calculating child support in Ontario for shared custody involves several steps. The Ontario Child Support Guidelines provide a formula to determine the appropriate amount based on:

The income of both parents
The number of nights each parent has custody of the child
The number of children
Other financial responsibilities

The calculator simplifies this process by using the official guidelines to provide an estimate. Keep in mind that actual court orders may vary based on specific circumstances.

Note: This calculator provides an estimate based on Ontario's child support guidelines. For exact amounts, consult a family lawyer or the Ontario Child Support Guidelines.

The Formula

The Ontario Child Support Guidelines use the following formula to calculate child support:

Child Support = (Parent 1 Income + Parent 2 Income) × Percentage × (Nights with Parent 1 / Total Nights)

Where:

Parent 1 Income - Income of the parent paying support
Parent 2 Income - Income of the parent receiving support
Percentage - The percentage from the Ontario Child Support Guidelines table
Nights with Parent 1 - Number of nights the child spends with Parent 1
Total Nights - Typically 365 nights per year

The percentage is determined based on the combined income of both parents and is provided in the Ontario Child Support Guidelines tables. The calculator uses these tables to determine the appropriate percentage.

Worked Example

Let's look at an example to understand how the calculation works.

Example Scenario

Parent 1 (paying support) income: $60,000
Parent 2 (receiving support) income: $50,000
Number of nights with Parent 1: 180
Number of nights with Parent 2: 185
Total nights: 365

Calculation Steps

Calculate combined income: $60,000 + $50,000 = $110,000
Determine the percentage from the Ontario Child Support Guidelines table for $110,000 (approximately 18%)
Calculate the base amount: $110,000 × 0.18 = $19,800
Adjust for custody nights: $19,800 × (180/365) ≈ $9,800

The estimated child support in this example would be approximately $9,800 per year.

Note: This is a simplified example. Actual child support amounts may vary based on specific circumstances and court orders.
